I am an active person with small ears. Wearing earbuds inside my ears is uncomfortable and doesn't allow me to hear ambient noise. I bought these as an alternative to my Shokz which are fantastic - except for the band around the lower part of my neck. These have a great fit. You hardly notice them. The sound is INCREDIBLE! I really like the pop of color (I chose the ruby ones). I read on another review that they seem to get tighter when you sweat. I did notice that as well. In a way, it made me feel more secure. I would hate for one of these to get lost on a run! Overall, I am happy with the purchase.

Owned for the Summer and love them! Perfect balance of great sound with still being aware of what's happening around you. Listen to your favorite show, catching all the dialogue and/or music at a HIGH level of quality. At the same time Not bothering your Significant Other. Hold conversations. Walk the dog. All safely since you can hear things coming, etc.

I have been using the headphones for over a month now and find it to meet my expectations based on Bose's high-quality standards. It presents a different slant in open back headphones! Well done and make it to three devices seamlessly and concurrently by way of a software update.

[This review was collected as part of a promotion.] I bought these while on a business trip. They are very comfortable, don't hurt my ears, and the sound is awesome. I don't like noise canceling earbuds so these let just enough outside noise in, that I still know what's going on around me.

[This review was collected as part of a promotion.] I bought the Lisa x Bose collaboration open earbud—it’s my first pair of open earbud, and I really like them! They’re amazing, and I hope there will be a full diamond version next time—that would be perfect!

[This review was collected as part of a promotion.] My husband bought the Sandstone color as a gift for me. I am absolutely in love with them. I have a child with a heightened sensory system and me listening to music is a trigger for her. Regular in ear earbuds are noise cancelling so I can't hear what's going on around me but the Ultra open earbuds allow me to hear what's going on around me and I can still have my music. For me, this is a game changer! I get the best of both worlds! These are 'Ultra' easy to use and the sound quality is incredible! Fast forward a few months, my other college age daughter used them while she was home on break and loved them for the same reason. She said these would be great to wear in the lounge areas because she can hear what's going on around her without getting too distracted. She also said that they would be great when she is walking on campus at night for that peace of mind of knowing what's going on around her. Needless to say, we bought her the Chilled Lilac for her birthday!

[This review was collected as part of a promotion.] I got my earbud for Christmas and I've been using it every day. I use it at work all day long and I use it when I go for my walk and rollerblading. Now I'm looking at one of the Bose headphone for meditation and traveling I need a quiet surround sound.

Great sound, great comfort, terrible functionality. They work great for a couple of days then go silent and I have to hard reset them to make them work again. Bose replaced them once, but the same issue recurred. It's truly frustrating that such a premium product behaves this way. The cheaper SHOKZ don't have this problem. *sigh*

[This review was collected as part of a promotion.] I got these for my birthday and they have been the best purchase/gift!! I even forget sometimes I have them on because of how comfortable they are, I can hear the music louder and clearer, plus they look great and people always stop me to ask me where I got them. I love them!!

[This review was collected as part of a promotion.] I bought these to try out the open earbud concept, and purchased refurbished to save some money since I heard good things about Bose's refurbished program. My other earbuds tend to fall out of my ears when I'm moving around or active, and these stay in place really well. I also really prefer to use the Bose Ultra Open Earbuds for meetings, so I can hear myself in the conversation in a more natural way, instead of only being able to use one earbud or hearing my own voice muffled in meetings previously. These are the most expensive earbuds I've ever purchased by far, but for around $200 refurbished I am very happy with them so far. I'm not sure I would pay the full new price, but I appreciate that refurbished is offered for that reason.
